The head office of LiuGong Group is located in Liuzhou City, south China's Guangxi Zhuang Autonomous Region. Founded in 1958, the company has developed at full speed for decades. Today, it is one of the leading enterprises of China's construction machinery and industrial equipment industries, thanks to the painstaking efforts made by its employees over the past few years. 

Sixty years ago, in response to the country's call for industrial construction, a large number of workers were transferred from Shanghai to Guangxi. Yang Guanmiao was one of them.
